Hi everyone,
I have a question about the solver. In the numerical block there are linear solver and non-linear solver. I’m doubting in which condition should I apply non-linear solver. In my model, only heat transport and groundwater flow processes are included. I’ve seen some examples in ogs5py benchmark but still cannot find a clue when a non-linear solver is applied. Appreciate it if anyone can answer this question.
Best,

Selection of solver depends on governing equations of each process and coupling of processes (e.g., H+M, HnM, HT, THM).
